SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 264,692, datedSeptember 19, 1882.

Application filed May 4, 1882.

To all whom it may concern Be it known that I, THOMAS T. HARRISON, ofAubrey, in the county ofJohnson and State of Kansas, have invented a newand useful 1mprovement in Sulky-Plows, of which the following is a full,clear, and exact description.

This improvement in sulky-plows consists of ajoint in the tongue atlittle in advance of the axle on which the wheels are mounted, and aboutwhere the evener is attached, for allowing the tongue to swing, so thatthe horses may get about half-way around square corners before the plowturns, together with stops by which the movement of-the tongue on saidpivot is limited to the required amount, said stops being changeable forallowing the tongue to be shifted in like manner on said pivot, eitherto the right or left hand. By thus allowing thetcam to turn about halfaround the corner before starting the plow and then pulling directlyahead in the direction of the fur row the plow comes into positionbetter than when the joint is behind the wheels, where it has commonlybeen located heretofore. The jointis also useful for wheel-cultivators;butin that case the stops are shifted so as to allow the tongue tovibrate both ways alike.

Reference is to be had to the accompanying drawings, forming part ofthisspecification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figurel is a plan view of my improved jointed-tongue contrivance forsulky-plows, together with the axle of the truck, also the whiffletrees,shown in dotted lines; and Fig. 2 is a perspective view of the tongueand the stops.

A represents the axle of the truck of the sulky-plow in dotted lines. Brepresents the part of the tongue attached to said axle, and G thetongue proper, to which the horses are hitched by the whiffletrees D andE. The said two parts of the tongue overlap each other in front of theaxle A, and are pivoted together at F, in about the middle of said lapand at the point where the evener D is attached. In practice the evenerwill be attached by the same bolt that forms the pivot F.

G and H represent the stops employed to (No model.)

limit the swing of tongue 0 on the pivot F. They consist of short flatbars bolted on part B, under part 0 of the tongue, with angles I Jturned up at the ends. They are located before and behind the pivot Frespectively, and the one before the pivot projects from the tongue inthe direction the horses take when turning at the corners, while the onebehind the pivot projects equally the other way, so that the tongue willbe stopped alike by the angles I before and behind the pivot. The anglesI are oblique to the bars whereonthey are formed, to beparallel to thetongue when it touches them; but the angles J are square to said bars,tobe parallel to the tongue when it is in line with part B, and form stopsto prevent the tongue from turning to the right hand when the stops areset for allowing it to turn to the left hand. If it be desired to allowthe tongue to swing the other waythat is,to therighthandthe stops areshifted lengthwise across the tongue to project in the oppositedirections, the angles I being in this case set parallel to the tongueB,which causes angles J to assume the oblique positions to correspondwith the tongue 0 when turned to the right. The said stops are also tohe attached centrally to the tongue 0 by holes L, when the truck is tobe used for a cultivator, to allow the tongue lateral play in bothdirections.

The contrivance is also useful for breakingplowsv with which wheels arenot used. In that case the part C ofthe tongue will be pivoted to thebeam of the plow in the same manner as it is here represented with thepart B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a sulky-plow, a tongue composed of the two parts B O, pivotedtogether, and provided with the stops G H I J, adjustably secured to thestationary part B, substantially as and for the purpose set forth.
